PLUME AND LEVEL GAGE.

Specification of Letters Patent.

Patented duly 2, 121..

Application filed August 20, 1917. Serial No. 187,239.

To all whom t may concern.'

Be it known that l, CHARLES BRIZENDINE, a citizen of the United States, residing at Stockton, county of San Joaquin, State of California, have invented certain new and useful improvements in Plumb and Level Gages; and l do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which forma part of this application.

ll`his invention relates to improvements in paraphernalia for plumbing and leveling any piece of construction work and the object of the invention is to provide a small attachment for use on a steel square where by the plumbing and leveling may be done in an easy, rapid and effective manner without the necessity of using any of the common forms of gages such as the bubble gage or the like. lVly improved invention consists of a small attachment which can be carried in the pocket of the user and when it is desired to plumb or level any work it can be easily and quickly attached to the steel square and the plumb and level determined in the manner set forth herein.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following` specification and claim.

ln the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is an elevation of a steel square showing my improved plumb and level gage thereon.

Fig. 2 is a perspective view of the independent attachment arranged to be af* xed to the steel square.

I Referring now more particularly to the characters of reference on the drawings the numeral 1 designates the s uare which can be of any desired type. y improved invention consists of a small plate2bifurcated as at 3 whereby it may be projected over the square l and fixed thereto by ,means of a set screw 4;. rlhe plate 2 is provided with an open slot 5 reduced at its ends to form notches as at 5a. When the plate 2 is fitted over the square l the distance from the inner edge of the square to the notch 5a is predetermined as say for instance one inch. When it is desired to use the device as a plumb gage the square 1 is set against the vertical structure desired to be made plumb and the plumb line 6 is then projected through the slot 5 and secured in the notch 5 (the line 6 being provided with a knot or other suitable holding means for the purpose). The position of the plumb bob 7 is then noted and if it points at the one inch indication on the other side of the square 1 this indicates that the structure is plumb. lf it does not point to the one inch indication then the structure may be altered until it is found to be plumb in the manner set forth above. Similarly the device may be used as a level by placing the lower side of the square on the structure to be leveled and likewise noting the position of the plumb bob 7.

From the foregoing description it will be readily seen that l have produced such a device as substantially fulfils the object of the invention as set forth herein.

`While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claim.

Having thus described my invention what l claim as new and useful and desire to sen cure by Letters Patent is:

A device of the character described com# prising a plate, a means for fixing the plate to a square, the plate being provided with a slot terminating inV a notch whereby a plumb line may be suspended therein.

ln testimony whereof l affix my signature.

CHARLES BRlZENDINE.
